URL Website Scanner

Scan any public website by URL. The page HTML is fetched via a CORS proxy and analyzed entirely in your browser. Checks for missing lang, title, skip links, landmark regions, heading hierarchy, image alt text, form labels, link text, button names, iframe titles, tabindex issues, and more — all against WCAG 2.2 criteria.

Why This Matters

URL scanning is the fastest way to audit a live website. This tool fetches the page HTML via a CORS proxy and runs 20+ WCAG checks entirely in your browser. For comprehensive analysis, use the axe-core deep scan option for 50+ WCAG 2.2 A/AA rules. You can also crawl up to 10 pages on the same domain.

Frequently Asked Questions

Why can't the scanner access my site?

The scanner uses CORS proxies to fetch page HTML. If your site blocks cross-origin requests, the proxy may fail. Try the HTML Scanner instead — paste your page source directly.

Does the scanner run JavaScript?

No. The scanner fetches the static HTML source. Single-page applications (React, Vue, etc.) may show minimal content. For JS-rendered pages, use the browser extension or paste the rendered HTML.

What's the difference between single-page and crawl mode?

Single-page scans one URL. Crawl mode follows same-domain links from the starting page, scanning up to 10 pages. Each page is scanned individually with results combined.

Is the scan data sent to a server?

No. The HTML is fetched via a public CORS proxy but all analysis happens in your browser. No data is stored on our servers.
